Ugororotse
Inzira ya Ethernet ihindagurika irashobora kumvikana nkumurongo wa matrix uhinduranya hamwe numurongo uhuza imirongo. Iyo paki yamakuru yamenyekanye kumurongo winjiza, paki yumutwe irasuzumwa, aderesi ya paki iboneka, imbonerahamwe yishakisha ryimbere iratangira, kandi icyambu gisohoka gihinduka. Ipaki yamakuru ihujwe no guhuza ibyinjira nibisohoka, kandi paki yamakuru ihuzwa neza nicyambu kijyanye no kumenya imikorere yo guhinduranya. Kuberako idakeneye kubikwa, gutinda ni bito cyane kandi guhinduranya birihuta cyane, ninyungu zayo. Ikibi ni uko kuva ibikubiye muri paki yamakuru atabitswe na enterineti ya Ethernet, ntibishoboka kugenzura niba paki yamakuru yatanzwe atariyo, kandi ubushobozi bwo kumenya amakosa ntibushobora gutangwa. Kuberako nta cache ihari, ibyinjira / ibisohoka ibyambu byumuvuduko utandukanye ntibishobora guhuzwa, kandi biroroshye gutakaza.
Bika kandi imbere
Ububiko nuburyo bwimbere nuburyo bwo gusaba murwego rwimiyoboro ya mudasobwa. Irabanza ibika data packet yicyambu cyinjira, hanyuma ikora CRC (cyclic redundancy code verisiyo) igenzura, ikuramo aderesi yerekanirwamo paki yamakuru nyuma yo gutunganya ikosa ryamakosa, ikayihindura mubyasohotse kugirango yohereze paki binyuze imbonerahamwe yo gushakisha. Kubera iyo mpamvu, gutinda kubika no kohereza mugutunganya amakuru ni binini, aribyo bibuze, ariko birashobora kumenya nabi paki zamakuru zinjira muri switch kandi bitezimbere cyane imikorere yurusobe. By'ingenzi cyane ni uko ishobora gushyigikira ihinduka hagati yicyambu cyumuvuduko utandukanye kandi igakomeza imirimo ikorana hagati yicyambu cyihuta nicyambu gito.
Gutandukanya ibice
Iki ni igisubizo hagati yabiri yambere. Igenzura niba uburebure bwamakuru paki buhagije kuri 64 bytes. Niba ari munsi ya 64 bytes, bivuze ko ari paki yimpimbano kandi paki yajugunywe; niba irenze 64 bytes, paki yoherejwe. Ubu buryo ntabwo butanga igenzura ryamakuru. Umuvuduko wacyo wo gutunganya amakuru yihuta kuruta kubika no kohereza, ariko bitinda kurenza pass. Kumenyekanisha guhinduranya kwa Hirschman.
Igihe kimwe, switch ya Hirschman irashobora kohereza amakuru hagati yicyambu kinini. Buri cyambu gishobora gufatwa nkigice cyigenga cyurwego rwigenga (icyitonderwa: igice cyumuyoboro utari IP), kandi ibikoresho byurusobe bihujwe nabyo birashobora kwishimira umurongo mugari wigenga utarushanijwe nibindi bikoresho. Iyo node A yohereje amakuru kuri node D, node B irashobora kohereza amakuru kuri node C icyarimwe, kandi byombi bifite umurongo wuzuye wumurongo kandi bifite aho bihurira. Niba ikoreshwa rya 10Mbps ya Ethernet ikoreshwa, traffic traffic yose ihwanye na 2x10Mbps = 20Mbps. Iyo 10Mbps isangiwe HUB ikoreshwa, traffic yose ya HUB ntizarenga 10Mbps.
Muri make ,.Hirschmanni umuyoboro wumuyoboro ushobora kurangiza umurimo wo gukusanya no kohereza amakuru kumurongo ukurikije kumenyekanisha aderesi ya MAC. Guhindura Hirschman birashobora kwiga adresse ya MAC no kubibika mumeza yimbere yimbere, kandi bigahita bigera kuntego binyuze muburyo bwigihe gito hagati yabatangije nuwakiriye intego yikarita.
